your patch works fine over here. are you sure your audio driver settings are correct? the reason you can here sound output from a quicktime movie before you set the @soc attribute, is because it is playing the audio through your system audio. when you set the soc, you are playing the audio through MSP, and must make sure your MSP settings are correct.

can you here any audio from MSP?

I had a fiddle with the DSP settings and it seems to be working now. I have another question though. How can I record sound from the second video as well? You cannot use the same soc attribute and I have tried adding an additional spigot with a different name but it still only records the audio from the first video. Any ideas?

Thanks for your help by the way.

make sure you've done the basic msp tutorials as well as the basic jitter tutorials.
